Floribunda rose variety &#39;POULfeld&#39;

ABSTRACT

A new garden rose plant which has abundant, white flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

[0001] The present invention constitutes a new and distinct variety ofgarden rose plant which originated from a controlled crossing made insummer 1985 between an unnamed seeding and an unnamed seedling. The twoparents were crossed and the resulting seeds were planted in acontrolled environment. The new variety is named ‘POULfeld’.

[0002] The new rose may be distinguished from its seed parent, anunnamed seedling hybridized by the same inventors, by the followingcombination of characteristics:

[0003] The seed parent has small white flowers, while ‘POULgeld’ haslarger white flowers.

[0004] The new variety may be distinguished from its pollen parent, anunnamed seedling created by the same inventors, by the followingcombination of characteristics:

[0005] The pollen parent is a patio rose with creamy, white flowerswhich are smaller than the flowers of ‘POULfeld’.

[0006] The objective of the hybridization of this rose variety forgarden use was to create a new and distinct variety with uniquequalities, such as:

[0007] 1. Uniform and abundant flowers;

[0008] 2. Vigorous, yet compact growth;

[0009] 3. Cold hardiness and disease resistance.

[0010] This combination of qualities is not present in previouslyavailable commercial cultivars of this type and distinguishes ‘POULfeld’from all other varieties of which we are aware.

[0011] As part of their rose development program, L. Pemille Olesen andMogens N. Olesen germinated the seeds from the aforementionedhybridization and conducted evaluations on the resulting seedlings in acontrolled environment in Fredensborg, Denmark. ‘POULfeld’ was selectedby the inventors in the spring of 1986 as a single plant from theprogeny of the aforementioned hybridization.

[0012] Asexual reproduction of ‘POULfeld’ by traditional budding wasfirst done by L. Pernille and Mogens N. Olesen in August, 1986. Thisinitial and other subsequent propagations conducted in controlledenvironments have demonstrated that the characteristics of ‘POULfeld’are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

[0013] The accompanying color illustration shows as true as isreasonably possible to obtain in color photographs of this type, thetypical characteristics of the buds, flowers, leaves, and stems of‘POULfeld’. Specifically illustrated in SHEET 1:

[0014] 1. Stem showing branching and the attachment of leaves, buds, andpeduncles;

[0015] 2. Flower bud, partially opened bud, and open bloom;

[0016] 3. Flower petals, detached;

[0017] Specifically illustrated in SHEET 2:

[0018] 4. Sepals, receptacle, and pedicel;

[0019] 5. Flowering stem as well as a bare stem exhibiting thorns;

[0020] 6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

[0021] The following is a description of ‘POULfeld’, as observed in itsoutdoor growth in a field nursery in Jackson County, Oregon.Observations were conducted during October, 1998. Color references aremade using The Royal Horticultural Society (London, England) ColourChart, 1995, except where common terms of color are used.

[0022] For a comparison, several physical characteristics of the rosevariety ‘POULander’, a rose variety from the same inventors describedand illustrated in U.S. Plant Pat. No. 6,265 and issued on Aug. 30, 1988are compared to ‘POULfeld’ in Chart 1.
